what you nedd is a x clamp repair kit that you can obtain easily
You will need
4x 12mm cheesehead screws.
16x 1mm thick steel washers.
16x 1mm thick nylon washers
masking tape
philips star screw deiver
two philips star screwdriver one small one large
small tip tweesers or thin straight for opening case
torx driver set
thermal compound paste
heatsink and cpu cleaner
cotton buds
You have to remove the heatsink for the gpu clean of all the old compound til the dyes on the gpu proccesor are like mirrors
then place the boardback in the case atach all the cables power button make sure the fan is hooked up
ballance the fan on the back of the case and one end of the fan and sit it over the cpu heatsink so that the fan is keeping the cpu heatsink cool while you onerheat the gpu
everything in place switch on
now this is important,when you switch on the fans are going to go rapid after two to three seconds the box will fire up all lights will either be in normall operation or will flash red at the bottom right and then switch to two flashing red lights the fans will then die out and box will turn this step has just switched and reset the gpu back to a working stage. pull out power cable leave for twenty minuts to cool enough then power up and you should now be sitting with a working console
now you should be ready to switch on
to prepar the new kit
remove the screw studs of from the heatsink and make sure its clean
now you have to put your new screws in place on the motherboard
use four screws 12mm ones put one steel washer and one nylon washer on each of the screws then carefully place them in the heatsink screw holes on the bottom of the motherboard then place masking tape over the screws to stop them from falling out when you turn the board over.
if you have done this right you should be looking at the top side of the board looking at the gpu proccesor and the new screws poping through. now place your remaining nylon and steel washers on the screws one nylon and one steel
now you want to put the heatsink compound on the chips dies. not to mush,silver is the best for it
once thats done carefully and gently put the heat sink in place hold the board in a way so that you can hold the heatsink and screw in the screws at the same time
screw into place making sure not to over tighten them just enough to take a good hold now your heatsink should be nicely in place held with the new screws and the fix complete
now reassemble everything and your done
happy gameing
